Abstract��
This article focuses on the analysis of geologic targets by applying multiple geophysical approaches including gravity��magnetic��mag- netotelluric (MT) detection and seismic exploration methods in Xingcheng areas of Liaoning�� The geophysical data were collected during fieldwork of the studied areas��using the methods men- tioned above and detailed analysis of the data were conducted�� The results show that gravity anomaly analysis plays an important role in geotectonic units division��identification of rift structure and basement relief; magnetic anoma- lies can be used to identify the rift structure and rock units with distinctive magnetic properties and analyse the igne- ous activities�� Magnetotelluric anomalies can significantly reflect the division of geotectonic units��distribution of faults and stratified layers�� Seismic exploration can be used to identify the geological boundaries and layers�� |
